晋陕蒙交界地区生态退化与恢复的研究现状和展望

晋陕蒙交界地区是我国生态环境破坏最严重的地区之一,当地所存在的植被退化、水土流失和土地沙化等一系列生态问题,不但威胁该地区居民的生存与发展,而且也影响我国东部地区的生态环境质量与经济发展。因此,开展针对该地区的生态恢复理论和恢复技术研究就显得非常重要。本文对该地区数十年来在生态恢复方面的理论研究和治理实践工作的历史和现状进行了分析,提出了今后应该加强对植被退化机理、植被恢复目标群落的确定和如何在大尺度地域上开展生态恢复等问题进行研究的建议,以便为更好地开展该地区的生态恢复工作提供帮助。

Current research status and prospects of ecological degeneration and restoration at the juncture of Shanxi,Shaanxi and Inner Mongolia

The region at the juncture of Shanxi,Shaanxi and Inner Mongolia is one of the most serious regions of ecological imbalance in China.A series of ecological issues in the region,such as vegetation degeneration,soil erosion,soil desertification,and so on,not only threatened local people's livelihood and development,but also affected the environmental quality and economical development of eastern China.Therefore,it is of significance to study the theory and technology of ecological restoration in the region.This paper analyzed the historical and current status of theoretical research and practical application of ecological restoration in the region,and put forward some suggestions on strengthening the researches of the mechanisms of vegetation degeneration,the determination of target communities for vegetation restoration,and the ways of carrying out ecological restoration on big scale area,which would benefit the development of ecological restoration in the region.
